should `guix deploy` work with dropbear?
on one of my servers i have replaced openssh with dropbear.
(service dropbear-service-type
(dropbear-configuration
(port-number 22)
(password-authentication? #false)
;; To allow `guix deploy` to connect as root.
(root-login? #true)))
i `guix deploy`ed the config, even rebooted the machine. all works fine, except
when i want to `guix deploy` once again:
$ guix deploy x.scm
The following 1 machine will be deployed:
lendvai
guix deploy: deploying to lendvai...
